Won't even return a call or several messages.

The service department is absolutely terrible with letting their clients know what is going on. With my car being only 2 years old and having gone for its second service in January which was also not up to scratch don't even get me started on the list of what they didn't do. My car started over heating last week to which I was towed to Suzuki on Friday morning. The last I got even an update was Friday afternoon. Without having a vehicle for the weekend and arranging lifts. I have been trying to phone them since 7.30 this morning and have left several messages to which nothing is answered at all. Ask to speak to a manager conveniently also too busy to take a call. All I want is a damn update is that too hard to understand??!! Or does Suzuki not care about their customers cause lately I feel that they the worst buy you can go for at the moment.
